Champ Programming was owned and operated by John W. Champeau. Champ made quite a few replicas of classic arcade games for DOS throughout the 1990s.
The company went out of business later on and all of its games were released
as freeware. Manfred Kremer created the CHAMPgames Fan Page (http://www.champ-em.com) as a tribute to the fallen Champ Programming company.
